  • European patent EP 57,002 entitled “Telescopic antenna mast” describes an apparatus whose value is solely to provide a telescopic system for devices at very elevated heights.
  • the current practice is to use a trellis system constituted of portions of metal profiles riveted and/or welded to each other.

  • FIG. 5 represents the top monobloc star antenna support
  • FIG. 6 represents a preferred Cardan joint

  • the invention resolves the above cited disadvantages and provides a novel conception of antenna support towers providing the following advantages:
  • the present invention pertains to the production of a high-performance antenna support tower with reduced costs of acquisition and use, contributing to better development of the environment and greater convenience and quality for the users.
  • the invention pertains to a wireless transmission device constituted by a tower, the upper part of which supports at least one antenna connected to electronic equipment comprising an HF amplifier, characterized in that said electronic equipment is located in the top part of the tower.
  • the electronic equipment is advantageously enclosed in a structured shelter integral with the tower.
  • the electronic equipment is preferably powered by photovoltaic cells located in the top part of the device.
  • the device comprises at its top part a rotary inertial mass producing gyroscopic stabilization.
  • the invention also pertains to a tower for wireless transmission which includes at least one flexible median shaft having at its top part a head located in a plane essentially perpendicular to the shaft, the shaft being equipped with articulated transverse spars, the tower comprising furthermore non-extensible means connecting the head, the spars and the base of the tower to form deformable parallelepiped modules, conserving essentially the parallelism of the spars, the head and the base.
  • the connecting means are constituted by at least two non-extensible braces arranged at either side of the shaft, attached at one of the ends to the base of the tower and at the other end to the head so as form a deformable parallelogram maintaining the head in an essentially constant plane.
  • the braces are preferably integral with each of the spars so as to form cells the bases and tops of which are maintained in parallel planes.
  • the spars are connected to the shaft by a recessed articulation along the axis of the shaft, and free in at least one transverse direction and pivoting in relation to at least one transverse axis.
  • the spars are constituted by essentially flat elements and the connecting means comprise 3 braces.
  • the spars are constituted by essentially flat elements and the connecting means comprise a multiplicity of flexible rods.
  • the head preferably has a faired part that can be oriented along a vertical axis.
  • the head is mounted freely in rotation and presents aerodynamic driving means for creation of gyroscopic stabilization.
  • the shaft is constituted by a multiplicity of elements that can be recessed.
  • the invention also pertains to a process for the installation of a tower comprising a lower conical element, characterized in that the conical element is installed, the top end of the conical element is equipped with a winch, the top element is hoisted up to a height allowing it to fit into the lower element and continuing on in this manner until reaching the segment intended to fit into the lower element of conical form.
  • a flexible support tower would be constituted according to the modalities below:
  • the central principal body is constituted by the tower itself, either in classic trellis form or as tubular sections or, for smaller sizes, as a single tube (monotube).
  • the sections are portions of telescopically fit together cones.
  • a base which is, e.g., circular or more simply square, is either bolted onto a solidly established structure or directly embedded or buried.
  • a central rigid star with three branches the ends of which function as top anchoring points for the tensioning devices (FIG. 5 ).
  • the three-branch star which functions as tensioning device is constituted of articulated horizontal arms (connecting rods), each along a horizontal axis tangential to a circle concentric with the central support.
  • These rigid arms are constituted in a monobloc manner or as a three-dimensional structure of the trellis type.
  • the successive arms are vertically coplanar such that only three vertical planes intersecting at 120° are sufficient to contain all of the planes of symmetry of the upper and intermediary branches (FIGS. 3 and 4 ).
  • these tensioning parts are immobilized at the level of the ends of the arms by parts of the packing box type through which passes the tensioning part of circular section such as, e.g., a cable. Locking of the nut makes it possible to interlock these elements.
  • the articulation of the top star in the preferred option is designed like the lower yoke of the Cardan joint which is integral with the end of the support tower and simultaneously locked in rotation.
  • the top yoke is integral with the diffusion and reception antennas irrespective of the form of this antenna support and is also locked in rotation by this fact.
  • the Cardan joint does not rotate in the manner of a movement transmission element between shafts.
  • the possible movements for the Cardan joint are only those of pivoting around the axes of the horizontal cross-piece (FIG. 5 ).
  • a mechanically equivalent system is that of a torque ball the joining piece of which would meet with the axis of the end of the support tower.
  • One possibility tending to diminish the drag of the assembly is that of providing for the positioning of the shelter in a clearly lower position without the level being such that the equipment would be exposed to vandalism.
  • the invention in the preferred option, the invention enables elimination of bracing wires. Nevertheless, even if in certain cases it is necessary to provide bracing wires, e.g., because of insufficient security of the foundations or desired limitation of flexion, the invention makes it possible to limit the extend of bracing and reduce the covered surface at the ground, as well as the number of attachment points.
  • the points of attachment to the tower can be limited to a low level rather than be distributed over the entire height of the tower.
  • the invention is distinguished by the implementation of special elements assuring the precision and security of assembly and durable operation:
  • the modalities of producing and using this assembly are themselves capable of many transpositions especially in relation to the general dimensions, installation and predicted weather conditions.
  • a simple conception of the central body is that of two or three superposed sections, bolted to each other by external straps. Even simpler, a monobloc body can be conceived when the transport conditions do not constitute an excessively unfavorable or unacceptable factor.
  • One certainly advantageous conception enabled by the invention is that already mentioned consisting of a central body comprised of multiple telescoping truncated sections, one particularly simple and useful arrangement of which consists of a robust assembly by straps or by a strap attached to the exterior of the lower part of the above section and a strap attached on the inside of the tube below in its top part.
  • Another variant concerns a device presenting a bottom trellis-like part upon which rests a top sectional part made of an envelope such as a tube.
  • Two devices can also be applied at the level of the top star to ensure free articulation: the first consists of an articulated cone, type of a flat ring arranged on inclined convergent feet and the second consists of an elastic lever similar to a joystick in form.
  • FIG. 6 represents a variant of implementation.
  • the device comprises a bearing shaft having a lower section ( 100 ) formed by a conical metal trellis extended by a multiplicity of sections ( 101 to 104 ) nested into each other.
  • the shaft supports at its top end a head ( 105 ) articulated such that it can pivot and move transversely.
  • the head 105 is also mounted freely in rotation and presents aerodynamic driving means for creation of gyroscopic stabilization, as shown by arrow A.
  • Braces ( 110 , 111 ) ensure the parallelism of the head ( 105 ) with the base of the device and maintenance of the head in an essentially constant plane, even when the shaft flexes under the action of the wind.
  • the spars ( 120 to 123 ) are articulated in relation to the shaft and form with the braces deformable cells, conserving the parallelism of the spars.
  • the top part has multiple platforms ( 130 , 131 ) maintained parallel by the braces ( 110 , 111 ) and articulated to enable pivoting and transverse displacement like the spars. These platforms allow placement of the antennas ( 132 ) and an HF amplifier 134 .
  • the shaft also supports a shelter( 140 ) enclosing the electronic equipment.
  • This shelter has a double skin to improve thermal exchanges.
  • Assembly is implemented by first installing the conical trellis structure ( 100 ). Then a winch is installed at the top part of this structure ( 100 ). The winch hoists up the top section ( 103 ) equipped with the head until its base reaches a height allowing it to fit into the lower section ( 102 ). This operation of hoisting with the winch the newly introduced section to place the following section is repeated until the shaft is finally raised.
  • the braces are attached on the head at the beginning of the operation and serve as bracing during the provision phase. They are then subjected to a slight stress to equilibrate the shaft.
